Finally, recent work has begun to uncover the perceptual tasks that underlie more complex comparisons, such as judging the correlation between two sets of paired values [1]}, [2]}, [3]}. This work suggests that, instead of judging high-level properties like correlation per se, a viewer relies on a more concrete proxy, such as the aspect ratio of the bounding box surrounding the points [3]}. These hypothesized proxies may prove to be complex and may take many years to unpack – but when they are better understood, we cannot predict whether they would be best supported by position encodings.
